VRI photometry of stars in 12 BL Lac objects
Listed in IVOA Registry (Virtual Observatory)
We present VR_cI_c Johnson-Cousins magnitudes of field comparison stars for twelve BL Lacertae objects belonging to the more large sample of blazars which is monitored at Perugia Astronomical Observatory.
Description
These comparison stars can be used in the long-term CCD photometric monitoring of BL Lac objects aimed to understand the characteristics of their variability. Finding charts for all of these comparison sequences are also included in this paper.
For a description of the (RI)c photometric system, see e.g. the General Catalog of Photometric Data <GCPD/54>
